| * ossl_store_handle_load_result() is initially written to be a companion |
| * to our 'file:' scheme provider implementation, but has been made generic |
| * to serve others as well. |
| * |
| * This result handler takes any object abstraction (see provider-object(7)) |
| * and does the best it can with it. If the object is passed by value (not |
| * by reference), the contents are currently expected to be DER encoded. |
| * If an object type is specified, that will be respected; otherwise, this |
| * handler will guess the contents, by trying the following in order: |
| * |
| * 1. Decode it into an EVP_PKEY, using OSSL_DECODER. |
| * 2. Decode it into an X.509 certificate, using d2i_X509 / d2i_X509_AUX. |
| * 3. Decode it into an X.509 CRL, using d2i_X509_CRL. |
| * 4. Decode it into a PKCS#12 structure, using d2i_PKCS12 (*). |
| * |
| * For the 'file:' scheme implementation, this is division of labor. Since |
| * the libcrypto <-> provider interface currently doesn't support certain |
| * structures as first class objects, they must be unpacked from DER here |
| * rather than in the provider. The current exception is asymmetric keys, |
| * which can reside within the provider boundary, most of all thanks to |
| * OSSL_FUNC_keymgmt_load(), which allows loading the key material by |
| * reference. |
